Specification of Letters Patent.

Patented May 20, 1913.

Application filed November 27, 1912. Serial No. 733,914.

To all whom it may concern Be it known that I, Josnrn L. NYLANDER, acitizen of the United States, residing at Seattle, in the county of Kingand State of Washington, have invented certain new and usefulImprovements in Electric Heaters; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to electric heaters for flowing water; anditconsists in the novel construction and combination of the partshereinafter fully described and claimed whereby the heater is speciallyadapted for hospital use.

In the drawings, Figure 1 is a side view partially in section, showing aheater constructed according to this invention. Fig. 2 is an end view ofthe heater.

The water is heated in a flexible pipe 2 formed of india rubber or othersuitable The pipe 2 is provided with a catheter or spray nozzle 3 asordinarily used for administering injections.

In order that the water may be delivered hot, the heater is applied tothe water pipe 2 as close as possible to its nozzle, and it is slidableupon the said pipe. A metallic heating tube 4 is arranged to slide incontact with the water pipe 2, and a suitable electrical resistance bodyor coil 5 is arranged around the heating tube and is provided withcircuit wires 7 and S, which are connected to an electric lightingfixture or other convenient source of electric current.

Caps 10 of insulating material are secured upon the ends of the heatingtube d, and 12 to the body of the patient. The cylinder of wire gauzeprotects the bed clothing, and the heated air escaping from it indicatesto the hand when the heater is working properly.

The flexible water pipe can be renewed as often as necessary.

l Vhat- I claim is:

In a device for administering injections, the combination, with aflexible pipe provided with a catheter at its outlet end, of a handle ofwire gauze encircling the said pipe, caps secured to the ends of thesaid handle, a heating tube secured to the'said caps and slidable bymeans of the said handle upon the flexible pipe, a resistance coilencircling the said heating tube, an air space being formed between theresistance coil and the handle, and a stiffening ring secured to themiddle part of the handle to prevent the wire gauze from being collapsedby the pressure of the hand.

In testimony whereof I have afiixed my signature in the presence of twowitnesses.
